It is composed of and.

(Problems to be Solved by the Invention) The device having the above-mentioned configuration has no problem in removing foreign matter of GS that has been cut into a short length as in the conventional case, but a strip-shaped long GS foreign matter removing apparatus. However, there are problems in the following points.

That is, when the above-mentioned device is applied to the strip-shaped long GS, it is difficult to synchronize the conveyance of the long GS and the driving motor, and therefore tension is generated in the GS and the GS is extended, or the gap between the GS and the slightly adhesive roller is increased. This causes slippage and scratches on the front and back surfaces of the GS.

In addition, when the conventional apparatus is used, there is a high possibility that foreign matter will adhere to the same place, and there is also a problem that the efficiency of removing foreign matter deteriorates immediately.

An object of the present invention is to provide a foreign matter removing device for a belt-shaped ultra-low tension sheet that can solve the above problems.
